ok strating to get cold here again and my truck is pretty rought at cold starts, i tryed the rev-x n helped little but not much, iv herd of ppl running
0w30 synthetic oil and it helping out alot. anyone done or know if a little thinner oil will help this, and wat is the cons of running a thinner synthetic oil? any chance of messing ne thing up? and if so wat oil and weight should i use? input would be awsome thanks.

Check your FICM voltage. There is a FICM repair procedure in the 6.0 Tech section.

If the FICM voltage is ok...which mine was....I ended up getting the "new" flash that has the inductive heating...it works well....if you're not keen on getting an update from the dealer (100$$) you can get power hungry performance (PHP) to flash the ficm with the Inductive heating and keep your older strategy (150$$)...

Sorry ment to include this in my first post... checked my ficm last week has 48volts all the way through cranking and did. A checked for injector codes with buzz test and all is good. And I herd with gearhead custom tunes I think it was might have been innovatives. It also updates the flash is this the same flash thanks

i lived in AK for last three years, i know all about cold starts.... anything above 20 degrees should not give you much issue, what temps we talking? Tunes will make cold starts much harder... i had to have eric custom work my tunes to eliminate cold start issues.. i have a bunch of differnt tunes i run, now i am in vegas and i am currently running a hotter DP tune, it will have cold start romps if its less then 50 degrees!! before you start troubleshooting injectors and such, go back to stock a tune, i bet it has no issues.... just call eric and tell him to work your tune... i had perfect starts in neg 20 with his tunes after he modified them to accommodate...

mine is doing the same thing but plumes like a locomotive with hi-idle on, stock is nothing. Still waiting to test ficm voltage as it is a pain to get it out. Eric told me to order rev-x and see what happens then he will work my tunes for me if needed.
